Worth grading — even a PSA 9 beats raw

A PSA 9 Magikarp & Wailord-GX sells for $2,603 against $173 raw: a $2,429 spread, 15× the ungraded price. Even a PSA 9 ($2,603) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
